C1144 INCOMPLETE STEERING ANGLE SENSOR ADJUSTMENT

Description

INFOID:0000000009949971

The steering angle sensor detects the rotation amount, angular velocity and direction of the steering wheel,
and transmits the data to the ABS actuator and electric unit (control unit) via CAN communication.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If “DTC CONFIRMATION PROCEDURE” has been previously conducted, always turn ignition switch OFF and
wait at least 10 seconds before conducting the next test.

>> GO TO 2.

2.

DTC REPRODUCTION PROCEDURE

1.

Turn the ignition switch ON.

2.

Select “ABS”, “WORK SUPPORT” and “ST ANG SEN ADJUSTMENT” in order with CONSULT, and per-
form adjust the neutral position of steering angle sensor.

C1145, C1146 YAW RATE/SIDE G SENSOR

C1145, C1146 YAW RATE/SIDE G SENSOR

Description

INFOID:0000000009949975

The yaw rate/side G sensor detects the yaw rate/side G affecting the vehicle, and transmits the data to the
ABS actuator and electric unit (control unit) as an analog voltage signal.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If “DTC CONFIRMATION PROCEDURE” has been previously conducted, always turn ignition switch OFF and
wait at least 10 seconds before conducting the next test.

>> GO TO 2.

2.

DTC REPRODUCTION PROCEDURE

1.

Turn the ignition switch ON.

2.

Perform self-diagnosis for “ABS” with CONSULT.

Is DTC “C1145” or “C1146” detected?

YES

>> Proceed to diagnosis procedure. Refer to 

BRC-64, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000009949977

CAUTION:

• Sudden turns (such as spin turns, acceleration turns), drifting, etc., when VDC function is off (VDC

OFF switch “ON”) may cause yaw rate/side G sensor system to indicate a malfunction. However, this
is not a malfunction, if normal operation can be resumed after restarting engine. Then erase memory
of self-diagnosis.

• If vehicle is on turn-table at entrance to parking garage, or on other moving surface, VDC OFF indica-

tor lamp may illuminate and CONSULT self-diagnosis may indicate yaw rate sensor system malfunc-
tion. However, in this case there is no malfunction in yaw rate sensor system. Take vehicle off of
turn-table or other moving surface, and start the engine. Results will return to normal.

INSPECTION PROCEDURE

1.

CHECK YAW RATE/SIDE G SENSOR POWER SUPPLY

1.

Turn the ignition switch OFF.

2.

Disconnect yaw rate/side G sensor harness connector.

3.

Check voltage between yaw rate/side G sensor harness connector and ground.

4.

Turn the ignition switch ON.

CAUTION:

Never start the engine.

5.

Check voltage between yaw rate/side G sensor harness connector and ground.
